How can I trigger / force sync iOS reminders?

Question

I am writing a mgmt task application using EKReminder. Works great when used on the same iOS device.

When I use on two devices (one Apple account), I understand that synchronizing synchronization of reminders with a significant delay and even often incomplete. (tried iCloud, google, company forecast)

So this is not related to my application (this happens if I change the reminders directly in the iOS reminder application).

Can I programmatically force synchronization of reminders with any service (for example, iCloud) with which they are connected and call it from my application?
